“…The reduced effect of repeated speech can be explained by invoking the Gestalt principle of similarity (cf. LeCompte & Watkins, 1993: perceptually similar stimuli are retained in primary memory as a group and can, at least to some extent, be ignored as a group. This idea is related to the concept of perceptual streaming, which has been applied to a number of findings in primary memory (see Jones, 1994, andLeCompte &Watkins, 1993).…”

The irrelevant speech effect is the impairment of task performance by the presentation of to-be-ignored speech stimuli. Typically, the irrelevant speech comprises a variety of sounds, but previous research (e.g., Jones, Madden, & Miles, 1992) has suggested that the deleterious effect of background speech is virtually eliminated if the speech comprises repetitions of a sound (e.g., "be, be, be") or a single continuous sound (e.g., "beeeeeee"). Four experiments are reported that challenge this finding. Experiments 1, 2, and 4 show a substantial impairment in serial recall performance in the presence of a repeated sound, and Experiments 3 and 4 show a similar impairment of serial recall in the presence of a continuous sound. The relevance of these findings to several explanations of the irrelevant speech effect is discussed.

“…These six findings have been mutually reinforcing, and it is fair to say that two-component theory has been widely accepted (Baddeley & Hull, 1979;Balota & Engle, 1981;Cowan, 1984;Engle, 1980;Greene, 1991Greene, , 1992Greene & Crowder, 1988;Greene, Elliott, & Smith, 1988;Harris, 1989;Nairne, 1990;Penney, 1985Penney, ,1989Penney & Godsell, 1993; M.

Indeed, to our knowledge it has never "been challenged.…”

The suffix effect is the reduction in the recallability of the last few items of a just-spoken list caused by appending a nominally irrelevant item, or suffix. The effect is widely assumed to comprise a "structural" terminal component, affecting just the last item, and a strategy-sensitive preterminal component. In a series of 8 experiments, the authors fail to replicate any of a variety of findings widely cited as the empirical basis for this 2-component theory. The authors also question the support that earlier findings provide for the theory, even if they had proved replicable. They attribute the entire suffix effect to the grouping of the suffix with the list items.

Four experiments investigated the acoustical correlates of similarity and categorization judgments of environmental sounds. In Experiment 1, similarity ratings were obtained from pairwise comparisons of recordings of 50 environmental sounds. A three-dimensional multidimensional scaling (MDS) solution showed three distinct clusterings of the sounds, which included harmonic sounds, discrete impact sounds, and continuous sounds. Furthermore, sounds from similar sources tended to be in close proximity to each other in the MDS space. The orderings of the sounds on the individual dimensions of the solution were well predicted by linear combinations of acoustic variables, such as harmonicity, amount of silence, and modulation depth. The orderings of sounds also correlated significantly with MDS solutions for similarity ratings of imagined sounds and for imagined sources of sounds, obtained in Experiments 2 and 3--as was the case for free categorization of the 50 sounds (Experiment 4)--although the categorization data were less well predicted by acoustic features than were the similarity data.
